Detailed Explanation of Apple Tree Management Techniques for May
Apple is a very common fruit and is grown on a fairly large area in China. Growing apples has also become a way for many people to make a fortune. As May approaches, apple management becomes increasingly important. Good management is the key to ensuring apple yields. So how should you manage in May? Below, the editor brings you the key apple management techniques for May. Let's take a look!
1. Spraying foliar fertilizer
Apple has a very high demand for fertilizers such as calcium and boron. About one month after the apple tree blooms, the demand for calcium rises sharply. Reasonable calcium supplementation can meet the apple's calcium needs. It can also enhance the quality and firmness of the fruit and reduce the incidence of pests and diseases. It prevents undesirable conditions such as water cracks and dehydration. So after flowering, we must pay attention to calcium supplementation. Then, at full bloom, pay attention to spraying boron fertilizer. This promotes pollen germination, increases fruit set, strengthens disease resistance, and improves growing returns.
2. Flower and fruit thinning
The purpose of flower and fruit thinning is to prevent the number of flowers and fruits from exceeding what the apple tree can bear. It reduces nutrient consumption, improves the fruit set rate of the apple tree, and prevents undesirable conditions such as alternate bearing. It can begin after the apple tree enters the bud stage, keeping one flower cluster about every 20cm on each branch. Then, after the flower clusters set fruit, thin out side fruits, small fruits and various deformed fruits, concentrating nutrients in the vigorous fruits. For trees that have not yet been pollinated, pollination must first be carried out. Then flower and fruit thinning should be done according to the actual situation.
3. Reasonable watering
In spring, to let spring shoots grow earlier, pay attention to watering the orchard about 7 days after flowering. Because flowering and fruiting consume too much water from the apple tree, water must be replenished in time. Then after entering May, stop watering to promote the growth of spring shoots. In June, the apple tree gradually begins flower bud differentiation, and at this time the amount of watering should be controlled as much as possible. So if you want to water again after April, it is generally done in summer. Therefore, everyone should water enough in April to ensure the water needs of the following two months are met, enhance the growth of spring shoots, and improve the flowering and fruiting rate.
4. Pest and disease control
May is also roughly the flowering period of apple trees, and this is also when pests and diseases do the greatest harm. So we should, according to the specific flowering time of the apple tree, pay attention to spraying fungicides and insecticides about 4 days before flowering. This suppresses the growth of pathogens, and spraying at this period is very important and must be thorough and complete. Then after flowering and before bagging, also pay attention to spraying agents to prevent fruit diseases, avoid damage to young fruits, and prevent a drop in yield. Observe the growth situation frequently, and when abnormalities are found, promptly check the cause and then take corresponding measures.
The above is a brief introduction to the key apple management techniques for May. Apple tree management is very important, especially during the spring flowering period. Poor management can severely reduce the flowering rate of apple trees, leading to lower yields and reduced growing returns. That is all for today's introduction. This article is for reference only.
